TUBULAR BOILER.

Specification of Letters Patent.

Patented June 13, 1916.

Application filed July 10, 1915., Serial No. 39,058.

To all whom it may concern Be it known that I, JOHN T. HAEUSSER, a

citizen of the United States of America, re-

siding in the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Tubular Boilers, of which the following is a specification.

My invention relates to tubular boilers, and the object of my invention is to provide a metallic conductor adapted to be inserted in tubes together with such other elements and combinations as are hereinafter more particularly set forth and claimed. I accomplish these objects by means of the mech anism illustrated in the accompanying drawing, in which with parts of the boiler broken away, show-- ing the tubes with my conductor placed therein.

Similar letters refer to similar parts throughout the several views. I

The boiler, C, is provided with a series of tubes, B, in the usual manner, through which the heat and gases of combustion pass, as indicated by the arrows, from the furnace, D, in the usual manner.

When the furnace is in operation the most intense heat conducted through each tube will be along its central line, that is, it is hotter midway between the sides of the tube than it is at the sides of the tube. A core of intense heat, so to speak, is formed along the central longitudinal line of the tube. In order that the heat thus formed may be conducted to the walls of the tube, I place a metallic conductor, A, into the tube extending as far as desired. The metallic conductor, A, is preferably bent so that two of its sides will approach each other, making the s ace between the two sides, o, 6, such, that t ey will come into contact with the hottest part of the stream or current of heat passing through the tube, B. Becoming very hot from its close association with the superheated portion, it will conduct the heat and bring it into contact with the walls of the tube, B, where the sides of the conductor, A, contact therewith as at f, g.

I make a series of holes, E, along the sides, a, b, of the conductor, A, which will tend to equalize the pressure of the burning gases on the sides of the conductor, and into the holes nearest the end a hook, not shown, may be inserted for withdrawing the conductor from the tube.

The. conductors, A, may be easily inserted into the tubes or removed therefrom when desired, their flexibility permitting of their being thus easily placed in position.

My invention may be used for cooling as 1 well as heating, for when it is desired to conduct the heat from the walls of a tube toward the center, thus coming in contact with air passing therethrough, the heat will be conducted from the walls, resulting in cooling t iem.

I do not limit myself to the construction the sides of the boiler tube, substantially as described.

In testimony whereof I have afiixed my signaturein presence of two witnesses.
